GEORGE IV. KORN, OF NEW YORK, N. Y.

POCKET-KNIFE.

SPECIFICATION forming part of Letters .Patent No. 273,858, dated March13, 1883,

Application filed October 2, 1882.

To all whom 'it may concern:

Be it known that I, GEORGE W. KORN, a citizen of the United States,residing at the city oi' New York, in the State of New York, haveinvented certain Improvements in Lock- Knives and Fly-Openers,of whichthe following is the specification.

The object ot` this invention is to produce a lock-knife and ily-openerthat is simple in construction, sate, and effective in operation.

Figure lis a side view ot' the knife open. Fig. 2 is a longitudinalsectional view, showling the form and position ot' the Hyopeniug spring;FigS is a longitudinal view through litio om of Fig. l, looking from thetop, as indcatetl by the arrow in Fig. 1. Fig. et is a perspective viewof the lock-level'.

Similar letters of reference refer to similar parts in the differentdrawings or figures.

A is the handle, having blade O' attached thereto by means of theordinary rivet..

Bisthe lock-lever, set inthe side ot' the handle, as shown in Fig.3.This lock-lever works upon the pivotH, which consists ot' a-pin passingdown through the side ot' the handle, as shown at H in Fig. l.

F, Fig. 3, is a spring located at the reareud of lock-lever B, and onthe under side thereof, and made to act outwardly.

D is the tlv-opening spring, located in the knife-socket in the handleand fastened to the handle at K.

I I are two pins in the front end of lock-le ver B, and are made toenter the holes E in the heel of the blade.

(No model.)

In using this knife, the blade being` closed, the spring D is compressedand the blade is prevented from flying open by the pins I I oflock-lever enteringr holes E in the blade, and the spring` F, actingoutwardly on the under side of rear end ot' lock-lever B, causes thefront end of the lever to press snugly against the side ot' blade O,andthe pins I I to remain in holes E. To open the blade, the rear end ofthe locklever is pressed downward, which lifts the pins I I from theholes E when the ily-opening spring D throws the blade O open and thepins I I are forced into the holes O in the blade, which rigidly holdsthe blade in an Open pOSlllOIl.

This form of construction of a knife of this character is very simpleand con'1parativel5T inexpensive, costing only the same as an ordinarv7pocket-knife.

I am aware that springs have been used to throw open the blade ot'knives, but not arranged and constructed or operating in the mannerherein shown.

I claim- The combination of the handle A, blade C, having holes O and Ein butt-end, the lock-lever B, working on pivot-pin H, having pins Ilinone end,actuated by the spring F at the other end, and the fly-openingspring D, all constructed and operating substantially as and for thepurpose shown.

GEORGE \V. KORN.
